species with us ; in fact, not a single typical specimen of bovis 

 is accessible. From these facts Dr. Cooper Curtice has, in con 

 versation with me, expressed the belief that bovis does not 

 occur in North America, but this would be in my judgment an 

 unjustified and rather rash conclusion to draw from the 

 specimens and experience which I have referred to. In con 

 nection, however, with the question raised in Insect Life by 

 Dr. Cooper Curtice as to whether the larvae are taken through 

 the mouth and subsequently penetrate to the skin, it may be 

 said positively that all his larvae found in the oesophageal walls 

 are of lineata, and this exceptional position of the larvae of this 

 species may have some connection with the exceptional habit 

 of the perfect fly of affecting and probably ovipositing upon 

 the heels of cattle. 



FURTHER NOTE ON CARPOCAPSA SALTITANS AND ON A 

 NEW GRAPHOLITHA PRODUCING JUMPING BEANS. 



BY C. V. 



In connection with my communication on this subject at a 

 previous meeting of the Society, I present an interesting letter 

 recently received from Professor Sereno Watson, of the Botanic 

 Gardens at Cambridge, Mass., as follows : 



' ' I enclose herein some ' critters ' that I found the other day 

 in an envelope containing the fruit of a Kuphorbiaceous shrub 

 from Northern Mexico, which we know for the present as 

 Sebastiania (?) bicapsularis. This fruit is very much like that of 

 a similar shrub which is reported to be the host of Carpocapsa 

 saltitans. Now, I am curious to know whether this is that in 

 sect or any relation to it, and I would also like to know whether 

 it is probable that these species of insects confine themselves 

 each to a single species or genus of plants, or whether they do 

 not more probably make use without distinction of the several 

 Kuphorbiaceous genera, which bear nearly identical capsules. 

 I have not ready access to the literature of the subject, and 

 now that Dr. Hagen is suffering from ill health I am sure that 

 you will pardon my troubling you with my questions." 



Prof. Watson's specimens enable me to speak with cer 

 tainty of the species which was referred doubtingly in my 

 previous communication to Carpocapsa saltitans as infesting the 

 capsules of what is marked in the Department Herbarium as 

 S. bilocularis, but which is doubtless the same as referred to by 

 Prof. Watson as bicapsularis. The specimens which h sends, 

 though rubbed, proved to be not C. saltitans, but an unde- 

 scribed species of Grapholitha, the Ian- a of which genus is 

 known to commonly infest seeds. It is not absolutely certain
